My 2010 Yukon has 20" factory chrome over aluminum rims. The finish if failing around the valve stems and where the original weights were. Ive tried every wheel refinishing shop in the area and not one shop will touch them. They all said they would have to be sent out to have the chrome removed and it would cost a fortune. Im just going to find a set of newer take offs in a 17 or 18" when the tires are a little more worn down.
